Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a wall-mounted air conditioner indoor unit and an air conditioner. Background Art

[0002] In a wall-mounted air conditioner indoor unit, an electric control box is usually arranged at the end of the internal space of the wall-mounted air conditioner indoor unit, such as the left end or the right end. However, with such an arrangement, the overall length of the wall-mounted air conditioner indoor unit will increase. On the one hand, it will lead to an increase in the materials used for the base, middle frame and panel of the air conditioner, increasing the cost of the air conditioner. On the other hand, it will also make it difficult to place the air conditioner in the indoor space.

[0003] Therefore, some existing wall-mounted air conditioner indoor units arrange the electric control box in front of the wind wheel motor, that is, on the side close to the main indoor space. However, with such an arrangement, the connection position between the electric control box and the component on which it is installed is not easily directly observable during assembly, which may reduce the operation convenience and increase the production time. Summary of the Utility Model

[0004] The first object of the utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of inconvenient assembly of the existing electric control box.

[0005] The wall-mounted air conditioner indoor unit provided by the utility model includes a base, a motor gland, an electric control box and an anti-retreat component. The electric control box is located in front of the motor gland; a first plug-in member is arranged on the base, the motor gland is fixedly installed on the base, and the motor gland is provided with a second plug-in member; the electric control box includes a box body, and the box body is provided with a third plug-in member that is respectively plugged and matched with the first plug-in member, and a fourth plug-in member that is plugged and matched with the second plug-in member; the plugging direction of the first plug-in member and the third plug-in member is parallel to the plugging direction of the second plug-in member and the fourth plug-in member; the anti-retreat component includes a matching first anti-retreat part and a second anti-retreat part, and the first anti-retreat part and the second anti-retreat part are used to prevent the electric control box from leaving the base and the motor gland along the reverse direction of the plugging direction. One of the first anti-retreat part and the second anti-retreat part is arranged on the electric control box, and the other is arranged on the base and / or the motor gland.

[0006] The beneficial effects brought by the wall-mounted air conditioner indoor unit of the utility model are:

[0007] By providing a first plug-in part on the base and a second plug-in part on the motor gland cover, which are respectively plugged into the third plug-in part and the fourth plug-in part on the electric control box. Moreover, the plugging directions of the first plug-in part and the third plug-in part, and the second plug-in part and the fourth plug-in part are parallel. Therefore, when installing the electric control box, only by moving the electric control box along this plugging direction can the plugging of the first plug-in part and the third plug-in part, and the second plug-in part and the fourth plug-in part be realized respectively, improving the convenience of installing the electric control box. And through the anti-retreat function of the first anti-retreat part provided on the electric control box and the second anti-retreat part provided on the motor gland cover and / or the base, the installation speed of the electric control box can be increased and the convenience of installing the electric control box can be improved. Moreover, the electric control box is connected not only to the motor gland cover but also to the base, which can improve the installation firmness of the electric control box compared to the situation where the electric control box is only connected to the motor gland cover.

[0008] In an optional technical solution, the first plug-in part includes a first plugging part and a first connecting part, and the first connecting part connects the base body of the base; the third plug-in part includes a second plugging part, and the second plugging part is connected to the box body, and the second plugging part is plugged into the first plugging part.

[0009] By providing the first connecting part to connect the first plugging part and the base body, a gap can be generated between the first connecting part and the base body, which is convenient for the second plugging part connected to the electric control box to be plugged into the first plugging part, avoiding the inconvenience of the plugging operation and the unplugging operation of the second plugging part and the first plugging part caused by the second plugging part being set at too low a position.

[0010] In an optional technical solution, the first plugging part is a male plugging part, and the second plugging part is a female plugging part; the width of the first plugging part is smaller than the inner wall spacing of the second plugging part, and a first guiding rib plate is provided between the inner walls of the second plugging part, and the first guiding rib plate matches the first plugging part, and the first guiding rib plate extends along the first insertion direction in which the first plugging part is inserted into the second plugging part.

[0011] By setting the width of the first plugging part to be smaller than the inner wall spacing of the second plugging part, the width of the second plugging part as the female plugging part is increased, which is beneficial to sharing the same plate between one side wall of the second plugging part and the box body. On the one hand, the material usage amount is reduced, and on the other hand, it can avoid the difficulty of injection molding caused by the too small spacing between two adjacent plates. And by providing the first guiding rib plate, when the inner wall spacing of the second plugging part is larger than the first plugging part, the two side walls of the first plugging part can be effectively limited, thus ensuring the connection accuracy.

[0012] In an alternative technical solution, a first chamfered portion is provided at the free end of the first insertion portion, and the first chamfered portion is located at the lower edge of the free end of the first insertion portion; along the first insertion direction, the thickness of the first insertion portion gradually decreases; and / or,

[0013] The first guiding rib plate is provided with a second chamfered portion, and the second chamfered portion is located at the inlet end of the first guiding rib plate. Along the first insertion direction, the distance between the second chamfered portion and its opposite surface gradually decreases.

[0014] By providing the first chamfered portion at the lower edge of the free end of the first insertion portion, the first chamfered portion can be used to abut against the bottom wall below the inlet of the second insertion portion, so that when the first insertion portion is inserted slightly lower than the preset position of the second insertion portion, in other words, when the second insertion portion is sleeved slightly higher than the preset position of the first insertion portion, it can play a guiding role in the relative movement of the two. Thus, it is convenient for the second insertion portion to be sleeved on the first insertion portion even when the two are not completely aligned.

[0015] By providing the second chamfered portion at the inlet end of the first guiding rib plate, when there is a slight deviation in the front-back position of the first insertion portion relative to the second insertion portion, the first insertion portion can be smoothly inserted into the second insertion portion. Moreover, by providing the second chamfered portion that can compensate for the front-back position deviation on the first guiding rib plate, the first insertion portion can have sufficient dimensions in the front-back direction, so as to achieve a relatively large matching length between the first insertion portion and the first guiding rib plate in the front-back direction, and improve the stability after the first insertion portion is inserted into the second insertion portion.

[0016] In an alternative technical solution, the first anti-withdrawal portion is configured to be insertable into the second insertion portion; the first anti-withdrawal portion includes a first cantilever, a first guiding-in portion, and a first anti-withdrawal surface. The first cantilever connects the first guiding-in portion and the first insertion portion. The first guiding-in portion is located in the first direction of the first insertion portion. The first guiding-in portion has a first guiding-in surface, and the first guiding-in surface is located on one side of the first guiding-in portion in the first direction. The thickness of the first guiding-in portion provided with the first guiding-in surface gradually decreases along the first insertion direction; there is a gap between the first guiding-in portion and the first insertion portion;

[0017] The second anti-withdrawal portion is an anti-withdrawal hole on the side wall of the second insertion portion, and the first anti-withdrawal surface is configured to abut against the hole wall of the anti-withdrawal hole; the first anti-withdrawal portion is configured such that when the gap between the first guiding-in portion and the first insertion portion decreases, the first anti-withdrawal surface disengages from the anti-withdrawal hole.

[0018] By utilizing the first cantilever to connect the first introduction part and the first plug-in part, since the first cantilever is not an absolutely rigid body, during the process of inserting the first introduction part into the second plug-in part, the first introduction surface of the first introduction part can be utilized to abut against the edge of the entrance end of the second plug-in part to compress the first introduction part, and the interval between the first introduction part and the first plug-in part is reduced, thereby deforming the first cantilever so that the first introduction part can be smoothly inserted into the second plug-in part, and the first stop surface is utilized to abut against the hole wall of the stop hole, thereby realizing the stop locking of the first stop part.

[0019] If the electric control box needs to be removed, the first stop portion can be pressed through the stop hole, thereby reducing the interval between the first introduction portion and the first plug-in portion, so that the first stop surface is separated from the stop hole, thereby releasing the stop function of the first stop portion and the second stop portion, so that the first stop portion and the first plug-in portion can be pulled out of the second plug-in portion. Therefore, the first cantilever is used to connect the first introduction portion and the first plug-in portion, which is not only conducive to more conveniently inserting the first plug-in portion and the first stop portion into the second plug-in portion, but also convenient for releasing the stop lock of the first stop portion and the second stop portion.

[0020] In an optional technical solution, the second connector includes a connector hole arranged on the connecting block of the motor cover, and the fourth connector includes a third connector and a second connecting part, the second connecting part connects the third connector and the box body; the third connector includes an insertion plate and a second guide rib perpendicular to the insertion plate, and the third connector is inserted into the connector hole.

[0021] By connecting the third plug-in part to the box body through the second connecting part, the second connecting part can be used to increase the distance between the third plug-in part and the box body. Then, the force acting on the third plug-in part of the electric control box and the second plug-in part can have a greater advantage relative to the box body. Under the condition of the same force, a larger torque can be generated to better fix the electric control box.

[0022] In an optional technical solution, the first stop portion is configured to be inserted into the plug-in hole; the first stop portion also includes a second cantilever, a second introduction portion and a second stop surface, the second introduction portion is located in the second direction of the third plug-in portion, the second introduction portion has a second introduction surface, the second introduction surface is located on the second direction side of the second introduction portion, the thickness of the second introduction portion where the second introduction surface is provided gradually decreases along the second insertion direction, the second cantilever connects the second introduction portion and the box body; the second stop portion is a stop groove provided on the hole wall of the plug-in hole, and the second stop surface is configured to abut the groove wall of the stop groove.

[0023] The second cantilever is used to connect the second introduction part and the third insertion part. Since the second cantilever is not an absolute rigid body, during the process of inserting the first introduction part into the insertion hole, the second introduction surface of the second introduction part can be used to abut against the edge of the entrance end of the insertion hole, compressing the second introduction part, reducing the interval between the second introduction part and the third insertion part, so that the second cantilever deforms, enabling the second introduction part to be smoothly inserted into the insertion hole, and using the second anti-retreat part to abut against the groove wall of the anti-retreat groove, thereby realizing the anti-retreat locking of the first anti-retreat part.

[0024] In an alternative technical solution, the first anti-retreat part further includes a third cantilever. The second cantilever and the third cantilever are respectively located on opposite sides of the second introduction part. There is a gap between the second cantilever and the second guiding rib plate. The second cantilever is configured such that when the gap between it and the second guiding rib plate decreases, the second anti-retreat surface disengages from the anti-retreat groove.

[0025] By arranging a third cantilever on the other side of the second introduction part and leaving a gap between the third cantilever and the second guiding rib plate, when it is necessary to remove the electric control box, the third cantilever moves towards the second guiding rib plate, so that the second anti-retreat surface disengages from the anti-retreat groove, releasing the anti-retreat locking of the first anti-retreat part and the second anti-retreat part, and the third insertion part can be withdrawn from the insertion hole.

[0026] In an alternative technical solution, a fifth insertion part connected to the base body is further provided on the base. The electric control box is also provided with a sixth insertion part. The fifth insertion part is a male insertion part, and the sixth insertion part is a female insertion part; the fifth insertion part includes an insertion column, and the insertion column is inserted into the sixth insertion part.

[0027] By arranging an insertion column on the base to be inserted into the fifth insertion part, the connection between the base and the electric control box can be enhanced, and the positioning of the electric control box can be achieved directly by these two connections between them, improving the installation stiffness of the electric control box.

[0028] The second object of the present utility model is to provide an air conditioner to solve the technical problem of inconvenient assembly of the electric control box.

[0029] The air conditioner provided in the second aspect of the present invention includes an air conditioner outdoor unit and the wall-mounted air conditioner indoor unit according to any one of the above. The air conditioner outdoor unit is connected to the wall-mounted air conditioner indoor unit through a refrigerant connection pipe.

[0030] By arranging the above-mentioned wall-mounted air conditioner indoor unit in the air conditioner, correspondingly, the air conditioner has all the advantages of the above-mentioned wall-mounted air conditioner indoor unit, which will not be elaborated here one by one.

[0049] Embodiment 1:

[0050] Figure 1 It is a schematic structural diagram of the wall - mounted air - conditioner indoor unit provided in Embodiment 1 of the present utility model, in which all the wall - mounted air - conditioner indoor unit drawings in this embodiment omit the middle frame and the front panel; Figure 2 It is a schematic structural diagram of the wall - mounted air - conditioner indoor unit provided in Embodiment 1 of the present utility model observed from another direction; Figure 3The structural schematic diagram of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model is observed from another direction; as Figures 1 - 3 shown, the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model includes a base 300, a motor gland 100, an electric control box 200 and an anti-retreat component. The electric control box 200 is located in front of the motor gland 100; a first plug-in part 310 is provided on the base 300, the motor gland 100 is fixedly installed on the base 300, and the motor gland 100 is provided with a second plug-in part 110; the electric control box 200 is provided with a third plug-in part 220 that is respectively plugged and matched with the first plug-in part 310, and a fourth plug-in part 230 that is plugged and matched with the second plug-in part 110; the plugging direction of the first plug-in part 310 and the third plug-in part 220 is parallel to the plugging direction of the second plug-in part 110 and the fourth plug-in part 230; the anti-retreat component includes a matched first anti-retreat part and a second anti-retreat part. The first anti-retreat part and the second anti-retreat part are used to prevent the electric control box 200 from leaving the base 300 and the motor gland 100 in the reverse direction of the plugging direction. One of the first anti-retreat part and the second anti-retreat part is arranged on the electric control box 200, and the other is arranged on the base 300 and / or the motor gland 100.

[0051] By providing the first plug-in part 310 on the base 300 and the second plug-in part 110 on the motor gland 100, which are respectively plugged with the third plug-in part 220 and the fourth plug-in part 230 on the electric control box 200, and moreover, the plugging direction of the first plug-in part 310 and the third plug-in part 220 is parallel to the plugging direction of the second plug-in part 110 and the fourth plug-in part 230. Therefore, when installing the electric control box 200, only by moving the electric control box 200 along this plugging direction, the plugging of the first plug-in part 310 and the third plug-in part 220, as well as the plugging of the second plug-in part 110 and the fourth plug-in part 230 can be respectively realized. And through the anti-retreat function of the first anti-retreat part arranged on the electric control box 200 and the second anti-retreat part arranged on the motor gland 100 and / or the base 300, the installation speed of the electric control box 200 can be increased, and the convenience of installing the electric control box 200 can be improved. Moreover, the electric control box 200 is not only connected to the motor gland 100, but also connected to the base 300. Compared with the electric control box 200 only being connected to the motor gland 100, the installation firmness of the electric control box 200 can be improved.

[0052] In this embodiment, the wall-mounted air conditioner indoor unit includes a base 300, a middle frame (not shown in the figure), and a front panel (not shown in the figure). When the wall-mounted air conditioner indoor unit is installed indoors, it is necessary to first fix a wall-mounted plate (not shown in the figure) on the wall, for example, nailed to the wall, and then hang the main body of the wall-mounted air conditioner indoor unit on the wall-mounted plate. Among them, the base 300 is the part of the wall-mounted air conditioner indoor unit for installing on the wall-mounted plate. The middle frame is installed on the base 300, and a heat exchanger 400 is arranged inside the middle frame, and the heat exchanger 400 is installed on the base 300. The front panel is installed on the middle frame. The electronic control box 200 is located between the motor gland 100 and the middle frame.

[0053] In this embodiment, it is described by taking the electronic control box 200 being arranged in the right half of the wall-mounted air conditioner indoor unit as an example. Therefore, when installing the electronic control box 200, it is necessary to move the electronic control box 200 from right to left. However, it does not prevent the electronic control box 200 from being arranged in the left half of the wall-mounted air conditioner indoor unit. Naturally, when installing the electronic control box 200, it is necessary to move it from left to right. In addition, the box body 210 includes a box base and a box cover. The third plug-in part 220, the fourth plug-in part 230, and the sixth plug-in part 250 are all arranged on the box base.

[0054] It should be noted that the first anti-retreat part and the second anti-retreat part are only used to indicate the components of the anti-retreat assembly, so they are named like this. In fact, the first anti-retreat part and the second anti-retreat part can represent different parts, and are not absolutely limited to a single component or part, or having multiple components or parts with the same shape and structure. For example, in this embodiment, the first anti-retreat part can be the anti-retreat part arranged on the base 300 for cooperating with the second anti-retreat part arranged on the electronic control box 200, or can be the anti-retreat part arranged on the electronic control box 200 for cooperating with the second anti-retreat part arranged on the motor gland 100.

[0055] In addition, the first anti-retreat part can further include a connecting ear plate 241 arranged on the electronic control box 200. The connecting ear plate 241 is connected to the bottom of the front surface of the box body 210, and the connecting ear plate 241 is also connected to the box body 210 through a connecting rib plate 242 to improve the connection stiffness of the connecting ear plate 241. Through holes or notches are arranged on the connecting ear plate 241 for a male threaded connecting piece such as a screw or a bolt to pass through, and the male threaded connecting piece is threadedly connected to a threaded hole column 340 arranged on the base 300. Among them, the threaded hole column 340 can belong to the second anti-retreat part.

[0056] Figure 3 It is a schematic structural diagram of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention observed from another direction; Figure 4 It is a schematic structural diagram of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention with the electronic control box omitted; Figure 5Schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model after omitting the electronic control box and the motor gland; Figure 6 Schematic diagram of the structure of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; As Figures 3 - 6 shown, optionally, the first plug-in member 310 includes a first plug-in portion 311 and a first connection portion 312, and the first connection portion 312 is connected to the base body of the base 300; the third plug-in member 220 includes a second plug-in portion 221, and the second plug-in portion 221 is connected to the box body 210, and the second plug-in portion 221 is plugged into the first plug-in portion 311.

[0057] By providing the first connection portion 312 to connect the first plug-in portion 311 and the base body, a gap can be generated between the first connection portion 312 and the base body, so as to facilitate the plugging of the second plug-in portion 221 connected to the electronic control box 200 into the first plug-in portion 311, and avoid the inconvenience of the plugging operation and the unplugging operation of the second plug-in portion 221 and the first plug-in portion 311 caused by the second plug-in portion 221 being arranged at too low a position.

[0058] Among them, the first connection portion 312 can be arranged at the lower part of the base 300, and the first connection portion 312 extends upward or obliquely upward from the lower part of the base 300. The first connection portion 312 can adopt the form of intersection of multiple plates. On the one hand, the weight and material usage of the first connection portion 312 can be reduced, and on the other hand, the material thickness of each part of the base 300 can be made as consistent as possible. When the injection molding material solidifies, the solidification time of the material is similar, which is beneficial to making the surface of the injection molded product smoother and flatter.

[0059] As Figures 3 - 9 , Figure 6 Schematic diagram of the structure of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; Figure 7 Schematic diagram of the box seat of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; Figure 8 Schematic diagram of the box seat of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model observed from another direction; Figure 9 Partial cross-sectional view of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; optionally, the first plug-in portion 311 is a male plug-in portion, and the second plug-in portion 221 is a female plug-in portion; the width of the first plug-in portion 311 is smaller than the inner wall spacing of the second plug-in portion 221, and a first guiding rib plate 222 is provided between the inner walls of the second plug-in portion 221. The first guiding rib plate 222 is matched with the first plug-in portion 311, and the first guiding rib plate 222 extends along the first insertion direction of the first plug-in portion 311 inserted into the second plug-in portion 221.

[0060] By setting the width of the first plugging portion 311 to be smaller than the inner wall spacing of the second plugging portion 221, the width of the second plugging portion 221 as the female plugging portion is increased, which is beneficial for one side wall of the second plugging portion 221 to share the same plate with the box body 210. On the one hand, the material usage is reduced, and on the other hand, it can avoid the difficulty in injection molding caused by too small a distance between two adjacent plates. By providing the first guiding rib plate 222, when the inner wall spacing of the second plugging portion 221 is greater than that of the first plugging portion 311, the two side walls of the first plugging portion 311 can be effectively limited, thus ensuring the connection accuracy.

[0061] Specifically, in this embodiment, the width of the first plugging portion 311 refers to the dimension of the first plugging portion 311 in the front-rear direction. Similarly, the inner wall spacing of the second plugging portion 221 is also the dimension between the front wall and the rear wall of the second plugging portion 221. In this embodiment, since the connection ear plate 241 is further provided at the bottom of the electric control box 200, the rear wall of the second plugging portion 221 partially functions to connect the main body of the electric control box 200 and the connection ear plate 241. And the first insertion direction, in this embodiment, is the direction from left to right, while in Figure 7 and Figure 8 it is embodied as the direction from right to left in the figure.

[0062] The first guiding rib plate 222 protrudes horizontally from the inner sides of the front wall and the rear wall of the second plugging portion 221 and extends horizontally, and can extend from the position at the entrance of the space in the second plugging portion 221 to the inner end of the space of the second plugging portion 221. More specifically, the first guiding rib plate 222 can be located at the middle position or the position slightly below the middle in terms of height on the inner sides of the front wall and the rear wall of the second plugging portion 221.

[0063] Such as Figures 3 - 5 and Figures 7 - 9 shown, optionally, a first chamfer portion 313 is provided at the free end of the first plugging portion 311, and the first chamfer portion 313 is located at the lower edge of the free end of the first plugging portion 311; along the first insertion direction, the thickness of the first plugging portion 311 gradually decreases; and / or,

[0064] a second chamfer portion 223 is provided on the first guiding rib plate 222, and the second chamfer portion 223 is located at the entrance end of the first guiding rib plate 222, and the interval between the second chamfer portion 223 and its opposite surface gradually decreases along the first insertion direction.

[0065] A first chamfering portion 313 is provided at the lower edge of the free end of the first plugging portion 311. The first chamfering portion 313 can be used to abut against the bottom wall below the entrance of the second plugging portion 221, so that when the first plugging portion 311 is inserted slightly lower than the preset position of the second plugging portion 221, in other words, when the second plugging portion 221 is sleeved slightly higher than the preset position of the first plugging portion 311, it can play a guiding role in the relative movement of the two. Thus, it is convenient for the second plugging portion 221 to be sleeved on the first plugging portion 311 even when the two are not completely aligned.

[0066] A second chamfering portion 223 is provided at the entrance end of the first guiding rib plate 222, which can enable the first plugging portion 311 to be smoothly inserted into the second plugging portion 221 when there is a slight deviation in the front-back position of the first plugging portion 311 relative to the second plugging portion 221. Moreover, by providing the second chamfering portion 223 that can compensate for the deviation in the front-back direction position on the first guiding rib plate 222, the first plugging portion 311 can have sufficient dimensions in the front-back direction, so as to achieve a relatively large matching length between the first plugging portion 311 and the first guiding rib plate 222 in the front-back direction and improve the stability of the first plugging portion 311 after being plugged into the second plugging portion 221.

[0067] In this embodiment, the thickness of the first plugging portion 311 refers to the dimension of the first plugging portion 311 in the vertical direction. The dimension between the front and back surfaces of the first plugging portion 311 does not change significantly with the first insertion direction.

[0068] In this embodiment, first guiding rib plates 222 are provided on both the front and back side walls of the inner wall of the second plugging portion 221. Thus, the difference between the inner wall spacing of the second plugging portion 221 and the width of the first plugging portion 311 can be compensated. Then, the opposite surfaces of the second chamfering portion 223 of one first guiding rib plate 222 are the opposite surfaces of the second chamfering portion 223 of the other first guiding rib plate 222. That is, the rear surface of the second chamfering portion 223 of the first guiding rib plate 222 provided on the inner side surface of the front side wall of the second plugging portion 221 is the front surface of the second chamfering portion 223 of the first guiding rib plate 222 provided on the inner side surface of the rear wall.

[0069] In other implementations, the first guiding rib plate 222 may be provided only on the inner side surface of the rear wall of the second plugging portion 221 or only on the inner side surface of the front wall of the second plugging portion 221, which can also play a role in controlling the front-back position of the first plugging portion 311 relative to the second plugging portion 221 during the insertion process of the first plugging portion 311. Then, the opposite surface of the second chamfering portion 223 is the inner wall surface of the second plugging portion 221 that is opposite to the second guiding portion. Along the first insertion direction, the interval between the second chamfering portion 223 and its opposite surface gradually decreases, indicating that the second chamfering portion 223 and its opposite second chamfering portion 223 or inner wall surface form an opening that is larger on the outside and smaller on the inside. Among them, the outside refers to the entrance end of the second plugging portion 221 as the female plugging portion.

[0070] As Figures 3 - 5 and Figures 7 - 9 shown, optionally, the first anti-retreat portion is configured to be insertable into the second plugging portion 221; the first anti-retreat portion includes a first cantilever 321, a first guiding portion 322, and a first anti-retreat surface 323. The first cantilever 321 connects the first guiding portion 322 and the first plugging portion 311. The first guiding portion 322 is located in the first direction of the first plugging portion 311. The first guiding portion 322 has a first guiding surface 324, and the first guiding surface 324 is located on one side of the first guiding portion 322 in the first direction. The thickness of the first guiding portion 322 provided with the first guiding surface 324 gradually decreases along the first insertion direction; there is a gap between the first guiding portion 322 and the first plugging portion 311;

[0071] The second anti-retreat portion is a retreat prevention hole 224 on the side wall of the second plugging portion 221, and the first anti-retreat surface 323 is configured to abut against the hole wall of the retreat prevention hole 224; the first anti-retreat portion is configured such that when the gap between the first guiding portion 322 and the first plugging portion 311 decreases, the first anti-retreat surface 323 disengages from the retreat prevention hole 224.

[0072] By using the first cantilever 321 to connect the first guiding portion 322 and the first plugging portion 311, since the first cantilever 321 is not an absolute rigid body, during the process of inserting the first guiding portion 322 into the second plugging portion 221, the first guiding surface 324 of the first guiding portion 322 can be used to abut against the edge of the entrance end of the second plugging portion 221, compress the first guiding portion 322, and the gap between the first guiding portion 322 and the first plugging portion 311 decreases, so that the first cantilever 321 deforms, enabling the first guiding portion 322 to be smoothly inserted into the second plugging portion 221, and using the first anti-retreat surface 323 to abut against the hole wall of the retreat prevention hole 224, thereby realizing the anti-retreat locking of the first anti-retreat portion.

[0073] When the electronic control box 200 needs to be removed, the first anti-return portion can be pressed through the anti-return hole 224, thereby reducing the interval between the first guiding portion 322 and the first plugging portion 311, so that the first anti-return surface 323 is disengaged from the anti-return hole 224, to release the anti-return function of the first anti-return portion and the second anti-return portion, so that the first anti-return portion and the first plugging portion 311 can be pulled out from the second plugging portion 221. Therefore, adopting the first cantilever 321 to connect the first guiding portion 322 and the first plugging portion 311 is not only beneficial to more conveniently inserting the first plugging portion 311 and the first anti-return portion into the second plugging portion 221, but also facilitates releasing the anti-return lock of the first anti-return portion and the second anti-return portion.

[0074] Wherein, in this embodiment, the first guiding portion 322 is located above the first plugging portion 311, and the first guiding surface 324 is located on the upper surface of the first guiding portion 322, so the first direction is the upward direction. Correspondingly, the anti-return hole 224 is provided on the upper side wall of the second plugging portion 221.

[0075] Viewed from the front of the air conditioner, the first guiding surface 324 of the first guiding portion 322 is in a state where the left end is higher than the right end. And the first chamfering portion 313 presents a state where the left end is lower than the right end. Therefore, the first chamfering portion 313 is arranged at the lower edge of the free end of the first plugging portion 311 and cooperates with the first guiding portion 322, reducing the overall height of the first plugging portion 311 and the first anti-return portion at the free end, facilitating the insertion of the first anti-return portion and the first plugging portion 311 into the inlet end of the second plugging portion 221.

[0076] Certainly, in another implementation manner, the thickness direction of the first guiding portion 322 can also be the front-back direction, and the first guiding portion 322 can be located in front of the first plugging portion 311, then the first direction is the forward direction. Correspondingly, the first guiding surface 324 is the front surface of the first guiding portion 322. When the first guiding portion 322 is inserted into the second plugging portion 221, the first guiding portion 322 is squeezed by the inlet end of the second plugging portion 221 and will move backward to facilitate the insertion of the first guiding portion 322. The first guiding rib plate 222 is arranged on the inner side surface of the rear wall of the second plugging portion 221 to support the first plugging portion 311. Correspondingly, the anti-return hole 224 is arranged on the front side surface of the second plugging portion 221 for the first guiding portion 322 and the first anti-return surface 323 to be inserted and anti-returned. When the electronic control box 200 needs to be removed, the first guiding portion 322 needs to be pressed backward, so that the interval between the first guiding portion 322 and the first plugging portion 311 is reduced, so that the first anti-return surface 323 is disengaged from the hole wall of the anti-return hole 224.

[0077] Figure 10 It is a schematic structural view of the box seat of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model viewed from another direction; Figure 11The structural schematic diagram of the motor gland in the wall-mounted air conditioner indoor unit provided by the first embodiment of the present utility model. As Figure 7 , Figure 8 and Figure 10 , Figure 11 shown, optionally, the second connector 110 includes a socket hole 112 provided on the connection block 111 of the motor gland 100. The fourth connector 230 includes a third insertion portion 231 and a second connection portion 232. The second connection portion 232 connects the third insertion portion 231 and the box body 210. The third insertion portion 231 includes an insertion plate 233 and a second guiding rib plate 234 perpendicular to the insertion plate 233. The third insertion portion 231 is inserted into the socket hole 112.

[0078] By connecting the third insertion portion 231 and the box body 210 through the second connection portion 232, the distance between the third insertion portion 231 and the box body 210 can be increased by using the second connection portion 232. Then, the acting force of the third insertion portion 231 of the electric control box 200 on the second connector 110 can have a greater leverage relative to the box body 210. Therefore, under the same acting force, a greater torque can be generated to better fix the electric control box 200.

[0079] Moreover, by providing the second guiding rib plate 234 and the insertion plate 233, the weight of the third insertion portion 231 can be reduced. At the same time, by using the cooperation of the second guiding rib plate 234 and the socket hole 112, the contact area is reduced, thereby reducing the possibility of incomplete fitting or difficult insertion caused by an uneven surface in the surface-to-surface fitting.

[0080] In this embodiment, a third chamfer portion 235 is further provided at the free end of the insertion plate 233. Since the electric control box 200 in this embodiment moves from right to left for installation, the left end of the third chamfer portion 235 is lower than the right end. Of course, in Figure 7 and Figure 8 , the left end of the third chamfer portion 235 shown is higher than the right end because Figure 7 and 8 are to observe the situation behind the electric control box 200, and the direction is opposite to the front view.

[0081] Among them, in this embodiment, the second guiding rib plates 234 can be arranged on the insertion plate 233 in a substantially vertical direction. Each second guiding rib plate 234 extends in the horizontal direction and protrudes backward from the insertion plate 233. The second guiding rib plates 234 start from the free end of the insertion plate 233, and the protruding degree gradually increases, that is, the second guiding rib plates 234 are provided with a fourth chamfer portion 236 at this end to facilitate the insertion of the second guiding rib plates 234 and the insertion plate 233 into the socket hole 112.

[0082] The second connecting portion 232 includes a connecting plate 237 and a reinforcing rib plate 238. Among them, the connecting plate 237 connects the insertion plate 233 and the box body 210. The connecting plate 237 protrudes backward from the rear wall of the box body 210 and extends in the up-down direction. The reinforcing rib plate 238 is connected to the second guiding rib plate 234. More specifically, the reinforcing rib plate 238 is connected to the second guiding rib plate 234 in a one-to-one correspondence.

[0083] As Figure 7 , Figure 8 and Figure 10 , Figure 11 shown, optionally, the first anti-retreat portion is configured to be insertable into the insertion hole 112; the first anti-retreat portion further includes a second cantilever 271, a second guiding portion 272, and a second anti-retreat surface 273. The second guiding portion 272 is located in the second direction of the third insertion portion 231. The second guiding portion 272 has a second guiding surface 275. The second guiding surface 275 is located on one side in the second direction of the second guiding portion 272. The thickness of the second guiding portion 272 provided with the second guiding surface 275 gradually decreases along the second insertion direction. The second cantilever 271 connects the second guiding portion 272 and the box body 210; the second anti-retreat portion is an anti-retreat groove 113 provided on the hole wall of the insertion hole 112, and the second anti-retreat surface 273 is configured to abut against the groove wall of the anti-retreat groove 113.

[0084] The second cantilever 271 is used to connect the second guiding portion 272 and the third insertion portion 231. Since the second cantilever 271 is not an absolute rigid body, during the process of the first guiding portion 322 being inserted into the insertion hole 112, the second guiding surface 275 of the second guiding portion 272 can be used to abut against the edge of the entrance end of the insertion hole 112, compressing the second guiding portion 272. The interval between the second guiding portion 272 and the third insertion portion 231 is reduced, so that the second cantilever 271 is deformed, enabling the second guiding portion 272 to be smoothly inserted into the insertion hole 112, and the second anti-retreat portion is used to abut against the groove wall of the anti-retreat groove 113, thereby realizing the anti-retreat locking of the first anti-retreat portion.

[0085] When it is necessary to remove the electric control box 200, it is possible to approach the third insertion portion 231 through the guiding portion, so that the first anti-retreat surface 323 is disengaged from the groove wall of the anti-retreat groove 113, releasing the anti-retreat function of the first anti-retreat portion and the second anti-retreat portion.

[0086] Among them, in this embodiment, the second guiding portion 272 is located below the third insertion portion 231, the second guiding surface 275 is located on the lower surface of the second guiding portion 272, and the second direction is the downward direction. Specifically, during the installation process of the electric control box 200, the electric control box 200 moves to the left. If observed in the direction of Figure 7 and Figure 8 , the electric control box 200 moves towards Figure 7 and Figure 8move to the right in the illustration. The second guiding surface 275 contacts the inlet end of the insertion hole 112. The inlet end of the insertion hole 112 applies pressure to the second guiding surface 275, causing the second cantilever 271 to bend, so that the second guiding portion 272 moves upward, and the distance between the second guiding portion 272 and the third insertion portion above it is shortened. Thus, the second guiding portion 272 can cross a part of the inlet end of the insertion hole 112 until the second anti-retreat surface 273 exceeds the side wall of the anti-retreat groove 113, and then the second guiding portion 272 rebounds downward, and the second anti-retreat surface 273 abuts against the groove wall of the anti-retreat groove 113.

[0087] The second cantilever 271 is a plate-like structure with an arc-shaped bending part. The bending part is connected to the third insertion portion 231 and is located at the left end of the third insertion portion 231, that is Figure 7 and Figure 8 the right end in. So when the second guiding portion 272 encounters the edge of the insertion hole 112, the second cantilever 271 can deform, which is beneficial for the first anti-retreat portion and the third insertion part to be inserted into the insertion hole 112. Moreover, with the above shape of the second cantilever 271, it can cooperate with the third chamfered portion 235, reducing the overall height of the third insertion portion 231 and the first anti-retreat portion at the free end of the third insertion portion 231, facilitating the insertion of the first anti-retreat portion and the third insertion portion 231 into the insertion hole 112.

[0088] Of course, in another implementation manner, the third chamfered portion 235 is located at the lower part of the insertion plate 233 portion, and the second guiding portion 272 is located above the third insertion portion 231, then the second direction is the upward direction. Correspondingly, the second guiding surface 275 is the upper surface of the second guiding portion 272. When the second guiding portion 272 is inserted into the insertion hole 112, the second guiding portion 272 is squeezed by the inlet end of the insertion hole 112 and will move downward to facilitate the insertion of the second guiding portion 272.

[0089] Such as Figure 7 、 Figure 8 and Figure 10 、 Figure 11 shown, optionally, the first anti-retreat portion further includes a third cantilever 274. The second cantilever 271 and the third cantilever 274 are respectively located on opposite sides of the second guiding portion 272. There is a gap between the second cantilever 271 and the second guiding rib plate 234. The second cantilever 271 is configured such that when the gap between it and the second guiding rib plate 234 decreases, the second anti-retreat surface 273 disengages from the anti-retreat groove 113.

[0090] By setting the third cantilever 274 on the other side of the second introduction part 272 and leaving a gap between the third cantilever 274 and the second guide rib 234, when it is necessary to remove the electric control box 200, the third cantilever 274 is moved toward the second guide rib 234, so that the second stop surface 273 is disengaged from the stop groove 113, so as to release the stop lock of the first stop part and the second stop part, and the third plug-in part can be pulled out from the plug-in hole 112.

[0091] Since the third cantilever 274 and the second cantilever 271 are respectively located at the two ends of the second introduction portion 272, the end of the third cantilever 274 away from the second introduction portion 272 is a free end, and this end is located outside the plug hole 112. Figure 7 and Figure 8 The left end shown is the free end of the third cantilever 274, and the plug-in hole 112 is exposed, so that the operator can easily move the free end of the third cantilever 274 to drive the second stop surface 273 to move upward and break contact with the stop groove 113. Specifically in this embodiment, since the second introduction portion 272 is located below the third plug-in portion, the free end of the third cantilever 274 is moved upward.

[0092] like Figures 5 - 10 As shown, optionally, the base 300 is also provided with a fifth connector 330 connected to the base body, and the electric control box 200 is also provided with a sixth connector 250, the fifth connector 330 is a male connector, and the sixth connector 250 is a female connector; the fifth connector 330 includes a connector post 332, and the connector post 332 is plugged into the sixth connector 250.

[0093] By providing a plug-in column 332 on the base 300 to be plugged into the fifth plug-in component 330, the connection between the base 300 and the electric control box 200 can be strengthened. The electric control box 200 can be positioned directly by using the two interconnections between the two, thereby improving the installation rigidity of the electric control box 200.

[0094] Specifically, the plug-in column 332 may be a rectangular hollow column, and a third guide rib 331 is disposed outside the hollow column. A plurality of third guide ribs 331 are arranged along the outer circumference of the plug-in column 332, and the third guide ribs 331 extend along the first insertion direction. The protrusion height of the third guide rib 331 near the free end of the hollow column gradually decreases along the first insertion direction, that is, a fourth chamfered portion 236 is formed. Moreover, the third guide rib 331 may also function as a reinforcing rib.

[0095] The operating principle of this embodiment is:

[0096] When the electric control box 200 needs to be installed, move the electric control box 200 from right to left. The first connector 310, the third connector 220, and the fifth connector 330 move relative to the electric control box 200 to the right. In other words, the second connector 110 and the sixth connector 250 move relative to the base 300 to the left, and the fourth connector 230 moves relative to the motor gland 100 to the left.

[0097] When the first chamfered portion 313 of the first insertion portion 311 of the first connector 310 contacts the lower edge of the entrance end of the second insertion portion 221, the lower edge of the entrance end of the second insertion portion 221 presses the first chamfered portion 313 upward; when the first guiding surface 324 of the first guiding portion 322 contacts the upper edge of the entrance end of the second insertion portion 221, the upper edge of the second insertion portion 221 presses the first guiding portion 322 downward, and the first cantilever 321 bends. The first connector 310 continues to move relative to the second connector 110, and the first guiding rib 222 can guide the movement of the first insertion portion 311 in the second insertion portion 221. The first guiding portion 322 passes over the entrance end area of the second insertion portion 221, the first anti-receding surface 323 passes over the pore wall of the anti-receding hole 224, and the first guiding portion 322 rebounds upward, so that a part of the first guiding portion 322 is embedded in the anti-receding hole 224, and the pore wall of the anti-receding hole 224 anti-recedes the first anti-receding surface 323.

[0098] When the third chamfered portion 235 at the upper end of the insertion plate 233 of the fourth connector 230 contacts the upper edge of the entrance end of the insertion hole 112, the upper edge of the entrance end of the insertion hole 112 presses the third chamfered portion 235; when the second guiding surface 275 of the second guiding portion 272 contacts the lower edge of the entrance end of the insertion hole 112, the lower edge of the insertion hole 112 presses the second guiding portion 272, causing the second guiding portion 272 to move upward, and the distance between the second guiding portion 272 and the third insertion portion 231 decreases. The third chamfered portion 235 and the second guiding portion 272 continue to move relative to the insertion hole 112 to the left. During the movement, the second guiding rib 234 can guide the movement of the third insertion portion 231 in the insertion hole 112. The second guiding portion 272 passes over the entrance end area of the insertion hole 112, the second anti-receding surface 273 passes over the groove wall of the anti-receding groove 113, and the second guiding portion 272 rebounds downward. Thus, a part of the second guiding portion 272 extends into the anti-receding groove 113, and the groove wall of the anti-receding groove 113 anti-recedes the second anti-receding surface 273.

[0099] In addition, the fifth connector 330 is also inserted into the sixth connector 250, and the details are not described here. Although the above several insertion processes are introduced separately, they can actually be carried out simultaneously.

[0100] After the insertion process is completed, a male threaded connector such as a screw or bolt can be used to pass through the connecting ear plate 241 and connect to the threaded hole column 340 on the base 300 to finally complete the fixation of the electric control box 200.

[0101] When it is necessary to remove the electric control box 200, first screw out the male threaded connector from the threaded hole column 340. Then, press down on the first anti-retreat portion so that the first guiding portion 322 disengages from the anti-retreat hole 224, and the anti-retreat lock between the first anti-retreat surface 323 and the hole wall of the anti-retreat hole 224 is released. Then, relatively move the first plug-in member 310 out of the second plug-in member 110. In addition, it is also necessary to lift the free end of the third cantilever 274 upward to lift the second guiding portion 272 out of the anti-retreat groove 113, and the anti-retreat lock between the second anti-retreat surface 273 and the groove wall of the anti-retreat groove 113 is released. Then, relatively move the fourth plug-in member 230 out of the third plug-in member 220.

[0102] The above two processes can be carried out simultaneously or separately. When both of the above pulling-out processes are completed, the connection between the fifth plug-in member 330 and the sixth plug-in member 250 is also released.
